Temporary Segregated Areas (TSA) and Temporary Reserved Airspace (TRA) are airspaces of predefined dimensions within which activities require the reservation of airspace for the use of specific users (mainly military) during a determined period of time.

1.1Temporary Segregated Area (TSA)

Temporary Segregated Area is an airspace temporarily segregated and allocated for the exclusive use of a particular user during a determined period of time and through which other traffic will not be allowed to transit.

1.2Temporary Reserved Airspace (TRA)

Temporary Reserved Airspace is an airspace temporarily reserved and allocated for the specific use of a particular user during a determined period of time and through which other traffic may be allowed to transit under air traffic control (ATC) clearance.

1.3Fight Plan Buffer Zones (FBZ)

Since active TSAs cannot be crossed, Flight plan Buffer Zones (FBZ) have been established for pre-tactically bookable TSA-s to accommodate IFR flight planning. An FBZ will be activated only with the corresponding TSA. IFR flights should flightplan to avoid an active FBZ using the ATS route system or waypoints published in ENR 4.1 and 4.4 established for flight planning in Free Route Airspace. Flight plans can be filed up to the boundary of the FBZ when active.

1.4Information About the Activation of TSAs/TRAs

Information about the actual period and height at which activities take place in TSAs/TRAs are notified via eAUP/eUUP or is available on request from AMC Estonia (contacts are given on page ENR 1.9 p. 9.4).

Note: Graphical description of the areas listed in the table below is given on page ENR TRA.

2.1General

2.1.1 This low-level flight standard operating procedure (LLF SOP) for military jet aircraft is for flight units of the Estonian Air Force, NATO and other military partners, while flying between 500 ft and 2000 ftAGL, with airspeed over 250 ktIAS, in Estonian airspace.

2.1.2 The original document for standard operating procedures for military aircraft is available in full at the homepage of the Estonian Defence Forces: http://www.mil.ee/en/air_force

2.1.3 Any concern, observation or recommendation regarding low-level flying and the procedures should be sent to Estonian Air Force Flight Safety by email: flightsafety@mil.ee

2.1.4 Ämari Command and Reporting Post provides the information regarding low-level flying activity and the position of military aircraft to civil operators by phone when requested.

2.2Description of Low-level Flying Areas

There are four (4) low-level flying areas for military jet aircraft activities in the Estonian airspace (see ENR 6 chart ENR LFC).

2.3.3Requirements and Restrictions During Low-level Flying

2.3.3.2 Only two pairs of aircraft are allowed into each low-level flying area simultaneously.

2.3.3.3 The use of chaff/flares is prohibited.

2.3.3.4 Aerodromes (listed in Estonian AIP AD 1.3) located inside an activated low-level flying area shall be avoided by 1 NM horizontally, unless a written agreement has been made with the airfield administration.

2.3.3.5 Aerial sporting and recreational activities areas (Estonian AIP ENR 5.5) will be avoided by 1 NM at all times.

2.3.3.6 During low-level flight flying should be avoided over the congested areas of settlements or over an assembly of persons at a height less than 300 m (1000 ft) above the highest obstacle within a radius of 600 m from the aircraft.

2.3.4Navigation Warnings

2.3.4.2 Civil vessels must be avoided horizontally with a minimum distance of 1 NM.

2.4Activation of Low-Level Flying Areas

Low-level flying areas will be activated by NOTAM not later than 1 working day before the low-level flight.

2.5Communication

Tallinn Area Control Center (Tallinn ACC) or Tallinn Approach Control (Tallinn APP) are responsible for provision of the information for civil aircraft pilots during low-level flying activities, depending in who's area of responsibility the flight takes place.
